“Snap-in failed to initialize” : When trying to open Device Manager

Asked By Avalon Walker 0 points N/A Posted on - 07/29/2011

I always get this error message when I try to open my Device Manager manually using the Control Panel  the same thing goes when I tried to Run it using the command "devmgmt.msc" Under the Start Menu. This is so annoying, I need to open my Device Manager to do some changes on my computer.

Snap-in failed to initialize.
Name:Device Manager

“Snap-in failed to initialize” : When trying to open Device Manager

Hello Dear,

Thanks for sharing your problem with us.

Dear when we install any windows then all its programs and necessary files are registered in dll registers.

Every program has its own dll files.

Here it seems that your device manager's supporting dll file is missing or unreadable.

Kindly repair your that file.

Simply type "chkdsk" in DOS.

it will scan all your computer for file system errors.

And your problem will be resolved.

Thanks
